Abstract
The scanning mechanism of facsimile transmitter and receiver units are synchronized by comparing the relative positions of each of the scanning mechanism at a particular time. A variation in the rate of the scanning motion for one of the scanning mechanisms is then initiated and this variation is continued until a predetermined time corresponding to a substantial degree of coincidence in the scanning position of each of the scanning mechanisms. The variation in the rate of the scanning motion is a substantially ramp-like function of time.
